Abstract: A method for software management of DMA transfer commands includes receiving a DMA transfer command instructing a data transfer by a first processor device. Based at least in part on a determination of runtime system resource availability, a device different from the first processor device is assigned to assist in transfer of at least a first portion of the data transfer. In some embodiments, the DMA transfer command instructs the first processor device to write a copy of data to a third processor device. Software analyzes network bus congestion at a shared communications bus and initiates DMA transfer via a multi-hop communications path to bypass the congested network bus.

Abstract: A method for hardware management of DMA transfer commands includes accessing, by a first DMA engine, a DMA transfer command and determining a first portion of a data transfer requested by the DMA transfer command. Transfer of a first portion of the data transfer by the first DMA engine is initiated based at least in part on the DMA transfer command. Similarly, a second portion of the data transfer by a second DMA engine is initiated based at least in part on the DMA transfer command. After transferring the first portion and the second portion of the data transfer, an indication is generated that signals completion of the data transfer requested by the DMA transfer command.

Abstract: Apparatuses, computer readable mediums, and methods of building a k-dimensional tree (kd-tree) are disclosed. The method may include a first processor, for example a graphics processing unit (GPU), selecting a node to split in a depth first manner. The method may include the GPU splitting based on a split plane a node into a left node and a right node. The GPU may assign the left (right) node to the GPU when a number of polygons associated with the left (right) node is above a threshold and otherwise assign the left node to a second processor, for example a central processing unit (CPU). The CPU may build the kd-tree in a depth first manner. The GPU (CPU) may select a next node to split based on a last node assigned to the GPU (CPU) or by selecting a node that is currently in a local memory of the GPU (CPU).

Abstract: A mooring device is adapted for holding fast a water craft on a body of water. The mooring device includes a base designed for engaging the water craft, and an elongated rigid mooring pole. The mooring pole has a proximal end attached to the base, and a free end extending away from the base. The free end of the mooring pole is releasably anchored to an anchoring structure.
